Every new system update fixes some security issues that may be exploited by others, and although these problems may seem commonplace, keeping your phone up to date is always a very important thing.
Take Apple mobile phones, in recent years, in addition to normal updates, it will also push security patches to many old models, because the current era is too networked, and it is necessary to always put security in the first place.
However, not all versions are worth updating, because there are many versions that are not so good to use, so updating bad versions for safety feels like a bit too much to lose.
For example, the official version of iOS 15.4, when the update did bring problems such as battery life, resulting in a very poor consumer experience, so many users did not dare to update to the latest version at the first time.
But fortunately, the official version of iOS 15.4.1 has been launched for a period of time, from the user's feedback, fluency, signal and battery life three aspects are tending to be stable, feel that there are not too many flaws.
This has also led to many fruit powders being updated and upgraded, especially for users who use the iPhone 12 series and the iPhone 13 series, which has enhanced the user experience.
However, Apple's mobile phone has a routine, that is, after it has been upgraded to the latest version, it is difficult to return to the old version, and it can even be said that after the current version of the downgrade channel is closed, there is no way to go back.
When iOS 15.4.1 was officially pushed for a while, the channel of the iOS 15.4 official version has been officially closed.
In other words, once iOS 15.4.1 is installed, it is impossible to downgrade back to the previous iOS version, which is also one of the strategies adopted by Apple's mobile phones for security.
At the same time, Apple usually stops signing the old version of the software update after the release of the new version is also to encourage customers to keep the operating system updated, otherwise they stay in the old version, then the new version of the upgrade volume will be much less.
Although iOS 15.4 was well received at the beginning, it brought a highly anticipated mask unlock function, but then users used it for a period of time to find that the version will reduce the battery life level, so the downgrade is not a loss.
The main thing is that according to the performance of the official version of iOS 15.4, closing the downgrade channel will become very good for fruit fans, after all, it is necessary to say goodbye to the bad version.
On the one hand, the experience of the official version of iOS 15.4 is indeed not so friendly, and if there is a user who mistakenly ascends, then the experience will definitely become very poor.
Today's new versions, on the other hand, are adding new features and enhancing the fluency of the product itself, so the old version is basically not worth remembering.
Therefore, users who like toss can still put the direction to a new version, and if they don't like toss, they can update to the word-of-mouth version, and then use it for a long time.
Because today's iOS system is still in the updated stage, but from the performance of the iOS 15.5 beta, it may not be so good.
Although there are many new machine users who say that the temperature control after the update is better, there are also many users who use the iPhone X series and iPhone 11 efficiency and say that the heat generation is large.
In addition, the new beta version did not bring too many upgrade changes, and most of the new features added were aimed at overseas brands.
In this case, it is still recommended that you first stay in the iOS 15.4.1 version, and then decide whether to update after the official version.
After all, WWDC 2022 has been confirmed to open on June 6, when the iOS 16 system will debut.
That is to say, today's iOS 15 version is nearing the end, the future will be the world of iOS 16, then at this stage also needs users to make a choice.
The first choice is to consider whether to stay in the iOS 15 version, for which the author also recommends that models below the iPhone 12 series do not upgrade to a new version.
The second is to continue to upgrade, which is definitely recommended for new machines, can experience some changes, and hardware parameters can also keep up.
Summary: Every time Apple's iPhone is mentioned, many people will think of two points for the first time, one is a powerful A-series chip, and the other is a smooth and reliable iOS system. Only from the current situation, the iOS system may also be up and cherished.
